The Electoral College was created PRECISELY with this eventuality in mind, to ensure that one large state doesn't become the dog with the rest of the country being the tail. It's an important counter to any potential tyranny of the majority, as is the equal representation of the states in the Senate, as well as an important part of maintainng a Federal Republic as opposed to a Unitary state.

from alleged zeocon dupes snopes.com: "It's true that if California's vote totals were entirely removed from the equation then Hillary Clinton would lose her popular vote lead, but the logic of that assessment is somewhat flawed. One could, for example, arbitrarily remove the states of New York and Massachusetts from the vote count, docking Clinton roughly 2.6 million votes (and wiping out her popular vote win). Or one could similarly claim that Trump's electoral vote victory "came entirely from Texas," since if Clinton had taken the Lone Star state (and its 38 electoral votes), she would also have won the overall election."

the electoral college may only be one of several issues at play e.g., redistricting, winner take all, lost votes (e.g., Michigan, wtf?), etc.

Correct, but, as the article I linked to shows, California was the clear statistical anomaly, with a grossly disproportionate share of the popular vote going to Clinton, as opposed to her share in the rest of the country.
